Cl. 49-492 8 Claims ABSTRACT OF THEDISCLOSURE Window consisting of an outer frame and an inner frame bothmade up of hollow generally U-shaped sections opening toward the insideof the window with cover strips covering the open side of the frames.Interengageable elements are carried on the frames with some of those onthe inner frame being moveable, and actuating means on the inner frameincludes parts disposed inside the inner frame and connected to themoveable elements.

The present invention relates to a window frame having a profile ofmetal or synthetic material. With heretofore known window constructionsof this type, the mounting of the actuating bars and the actuatingelements pertaining thereto for the fittings cause considerabledifficulties. While fittings are available the parts of 'which requirelittle space when being assembled, there exists the drawback that withthese fittings the fitting elements have to be arranged in theinterlock, of the window. In view of the cutouts in the profile of theblind and wing frame, which cutouts become necessary, the manufacture ofthe Wll'ldOW frame is considerably increased in cost. Moreover, theactuating bars which are displaceable in the interlock have to belubricated from time to time. In this connection, it is unavoidable thatexcessive lubricant deposits at the edge of the window wing. This edgeis visible when the window is open and is not very appealing. Moreover,the curtains or drapes can easily be soiled thereby.

The present invention concerns a window arrangement swingable about oneedge at the side or tiltable about the lower edge between closed andopen positions. The window consists of an outer frame'for stationarymounting in a wall opening, and an inner frame which is moveable intoand out of the outer frame.

The frames are in the form of hollow profile sections with each framehaving the sections in abutting relation at the ends and interconnectedby angular connectors. The profile sections have channels which opentoward the inside of the window and are arranged with flanges on whichcover or trim strips can be mounted.

The inner frame and outer frame have inner engageable elements forholding the window closed and open providing pivot axes on which theinner frame can tilt, and at least some of the elements on the innerframe are moveable while actuating means for the moveable elements arecarried by the inner frame and include parts extending in the channel inthe inner frame.

It is, therefore, an object of the present invention to provide a windowframe which will overcome the above mentioned drawbacks.

It is another object of this invention to provide a window frameconstruction which will permit the installation of different types offitting and ventilating systems.

It is still another object of this invention to provide a window framewhich is simple in construction,

These and other objects and advantages of the present invention willappear more clearly from the following ice specification in connectionwith the accompanying drawings, in which:

FIG. 1 is an elevational view of the window according to the presentinvention looking at the window from the inside.

FIG. 2 is a cross section taken along the line II--II of FIG. 1.

FIG. 3 is a cross section along the line III--III of FIG. 1.

FIG. 4 is an isometric view of a window plug.

FIG. 5 is an isometric view of a follower for use in connection with thepresent invention.

FIG. 6 is an isometric view of a plug pin.

FIG. 7 is a fragmentary elevational view of the lower left-hand cornerof the window looking at the window from the inside and with the coverstrips removed.

FIG. 8 is a fragmentary elevational view of the lower left-hand cornerof the outer frame of the window looking from the inside of the windowand with the cover strip removed.

FIG. 9 shows the arrangement of the rotatable tiltable fitting on thewing frame.

FIG. 10 is a corner connection of the blind frame.

The objects outlined above have been realized by composing the blind andwing frame of a profile which is open at the inner side surface, whilesaid open profile has formed abutment strips to its open side whichabutment strips serve as cover interlock and as support for a coverstrip closing the open side of the profile. In view of the design of theprofile according to the present invention, the fitting elements can bearranged within the blind and wing frame. Inasmuch as they are locatedbelow the cover strips and thus are not visible from the outside, it isnot necessary to machine their surfaces. The corner portions can be madestrong and uncomplicated without weakening the corner connections of theblind and wing frame. As cover strips, preferably wooden strips areemployed. Wooden strips are poor heat conductors: and thus prevent theformation of condensation on the inner window frame. In other words, theheat-cold bridge is interrupted. Moreover, such cover strips can bearranged on the window frame while any type of wood may be employedwhich matches the interior. Even when solid wood is employed, suchpressure strip of wood remains in the lower price bracket because onlystrips are employed.

A further feature of the present invention consists in that the blindand wing frame which is composed of a profile open on the inner sidesurface is held together by corner connecting elements, which areinserted into the metal or synthetic profile and are connected theretoby an adhesive. Inasmuch as the profile is open on the inwardly locatedside surface, the areas to be provided with an adhesive can be coveredby an adhesive from the inside. These areas are not visible from theoutside so that a post-machining of the outer surface of the frame willnot be necessary at the abutting areas.

Instead of an adhesive connection, it is also possible when making theframe of steel and synthetic material to employ a welding connection.The profiles of the blind or wing frame which are cut for mitering arewelded together at the respective joints. Since the welding areas arenot visible from the outside, also in this instance the otherwisenecessary post-machining operations are not necessary. In order toprevent any interference of the corner connecting elements with theinstallation of the actuating members of the fitting, it is advisable soto design the window frame that the metallic or synthetic profile forthe blind and wing frame will have two chambers accessible toward theinside, of which one chamber will permit the insertion of the cornerconnecting elements while the other chamber will permit the installationof the actu ating members for the fittings. The inner chamber of theblind and window frame which is not subjected to any load by theactuating members of the fittings, may be filled with a heat damminginsulating material. This is not possible when a closed tubular profileis employed.

With a wing frame made according to the present invention, the windowlugs are preferably with the lug ears connected to the abutment stripsformed onto the frame profile. In view of this arrangement, the strengthof the wing frame is considerably improved. In order to permit theemployment of Wing frames for the left as well as for the rightabutment, it is advantageous to arrange the window lugs at the cornersof the frame profile.

The lug ears or extensions are designed for suspending and guidingactuating members of the fitting. In view of this design, the turningand tilting links and the actuating members do not require anyadditional connecting and guiding plates. In order to permit a powerinterlock between the actuating bars and the displaceable lug pins, thelug extensions are provided with a perforation in which there isarranged a follower which connects the actuating bar with the lug pin.The said follower is laterally guided between the abutment strip formedonto the frame profile and the sealing strip. It is advisable todetachably connect the follower to the actuating bar and to the lug pin.In view of this detachable connection, the actuating members can beinstalled with a considerably greater ease.

Referring now to the drawings in detail, the window frame shown in FIG.1 is a one-Wing window. It is composed of metallic profiles, forinstance aluminum profiles and forms a blind frame 1 and a wing frame 2.The wing frame 2 is by means of window lugs 14 rotatably and tiltablyarranged in the counter bearings 19, 20 and 23 arranged on the blindframe 1. The wing frame 2 is furthermore equipped with two fittings and11 of which the fitting 10 serves for opening of the wing frame 2,whereas fitting 11 serves for tilting the wing frame 2.

At the left side of the window in FIGURE 1, three plungers 16 arereceived in the sockets or counter bearings 19 illustrated, and can bewithdrawn therefrom so that the window frame will pivot about an axisdefined by the three plungers 16 at the right side of the window. Theplungers 16 at the right side of the window consist of two upperplungers that can be withdrawn from their sockets 19 and a lower plungerwhich permanently engages its socket 23 and which socket 23 is tiltableon a horizontal axis 24. Axis 24 is coaxial with a plunger 17 in aboutthe middle of the bottom of the window frame that can be inserted in itspertaining socket 20. To tilt the window about axis 24, plungers at theleft side of the window and the two uppermost plungers at the right sideof the window are withdrawn from their sockets. Withdrawing of the lastmentioned plungers from the sockets also inserts plunger 17 in itssocket and the window can then be tilted outwardly at the top.

As will be evident from FIGS. 2 and 3, the blind frame 1 and the wingframe 2 are made of a profile which is open on the inner side surface.The open side of this profile is covered by cover strips 5, 6 of woodwhich serves for stiffening or reinforcing the profile frame and forpreventing the formation of water deposits. As supporting surfaces forthe cover strips 5, 6, the open side of the profile has formed theretotwo abutment strips 3, 4. To the abutment strips 3, 4 are connected theextensions of the lugs 14, by means of screws or rivets 33. According tothis embodiment, the inner chamber of the profile for the wing frame 2is sub-divided into two chambers 12 and 13. Chamber 12 serves for theinsertion of the corner connecting elements 7, whereas chamber 13 servesfor mounting the actuating bars 8, 9 and the transmission partspertaining thereto for the fittings 10 and 11. The extension 15 isfurthermore arranged for mounting fittings 10 and 11 and of the jointlever 34 as well as for guiding the actuating bars 8 and 9. With theembodiment according to FIG. 2, the extension 15 has rotatablyjournalled thereon a roller 22 by means of which the actuating bar 8 islaterally guided.

FIGS. 3, 4, 5 and 6 show a different embodiment of the presentinvention. According to FIGS. 3, 4, 5 and 6 the actuating bar 9 isguided by a guiding strip 25 formed from the extension 15. The extension15 is furthermore provided with a perforation 26 in which there ismounted a follower 29, said follower establishing the power interlockconnection between the actuating bar 9 and the lug pin 16. Follower 29on one hand by means of pivot 10 engages corresponding bores of theactuating bar 9 and on the other hand by means of the angled-off end 31engages a recess 32 of pin 16. Pin 16 is longitudinally displaceable inbore 28 of the window lug 14. The passages 27 provided in the extension15 are intended for receiving the screws or rivets 33 intended for theconnection. The inner chamber of the profile, which is not placed underload by the actuating bars 8, 9 and the actuating members pertainingthereto, is filled with a heat damming substance, for instanceinsulating foam rubber material.

As will be evident from FIGS. 7 and 9, identical window elements 14 aremounted on the band and the actuating side of the wing frame 2. Theidentical design of the members 14, in addition to simplifying thekeeping of stock, has the further advantage that the window can beemployed on the building lot for left as well as right abutments. Thepins 16, 17 are employed either as pivot or as closure mandrel. Thewindow members arranged at the corners and in the center of the wingframe 2 are by means of the screws or rivets 33 connected to theabutment strips. The window elements also contribute to strengthening,i.e. reinforcing the pro file.

As will furthermore be evident from FIGS. 7, 8, 9 and 10, the individuallegs of frame 1 and frame 2 are out at the corners for mitering and areheld together by corner connecting elements 7. The corner connectingelements 7 are introduced into the interior of chamber 12 and are gluedto the profile by means of a metal adhesive. When employing largewindows, the corner connecting elements 7 may as shown in FIG. 10 alsobe aditionally screwed to the profile by means of screws 33. In thisconnection, it is advantageous to employ selfcutting thread screws. Thebottoms of the screws 33 are arranged below the cover strips 5, 6 andtherefore are not visible from the outside.

The operation of the window is the same as with heretofore conventionalwindow constructions. For purposes of opening the window, the handle 18arranged at the fitting 10 is turned into opening position. As a resultthereof, the pins 16 on the transmission side of the window frame 2 arepulled out of the stationary socket-s 19 by the actuating bars 8. Thewing frame 2 may now be opened by swinging it about the vertical pivotaxis at the opposite side of the window. When the wing frame 2 is to betilted outwardly from the top, prior to the opening of the wing frame 2,first lever 21 of the turning tilting fitting 11 is brought into FlG. 9position. In this connection, the pin 17 serving as tilting axis isdisplaced into the counter bearing or 'socket 20, while simultaneously,the two upper pins 16 at the right side of the window are displaced bymeans of the actuating bars 9 and pulled out of their respective counterbearings or sockets 19. Handle 18 at the left side of the window is thenactuated to withdraw the associated pins 16 from their sockets 19. Atthis time, plunger 16 at the lower right hand corner of the wing orinner frame is also tiltable with its support 23 about the pivot axis 24and cooperates with pin 17 in establishing the pivot axis at the bottomof the window.
